: This CB Hawk ICS controller keeps burning I/O module cards.It runs fine then when its down for awhile,then on start up it goes into prepurge then shuts down and reads O/I Module 9 Fault Detected.
You either have a power supply issue (check board edge connectors for clues and ensure a GOOD ground), or input/output device electrical overloads that the board circuit protection is not catching fast enough. Good luck.
